Square root of an integer | A C # program to find floor ( sqrt ( x ) ) ; Returns floor of square root of x ; Base cases ; Starting from 1 , try all numbers until i * i is greater than or equal to x . ; Driver Code
using System ; class GFG { static int floorSqrt ( int x ) { if ( x == 0 x == 1 ) return x ; int i = 1 , result = 1 ; while ( result <= x ) { i ++ ; result = i * i ; } return i - 1 ; } static public void Main ( ) { int x = 11 ; Console . WriteLine ( floorSqrt ( x ) ) ; } }
